Rob Young commented on NUTCH-479:
---------------------------------

Hi I've found a bug in this patch. If I search for  title:red OR"title:blue" I 
would expect it to be expanded to
+title:"red" title:"blue" but in fact it expands to +title:"red" "title:blue" 
so there is no way to do term specific queries.

> Support for OR queries
